早期关于数字认知的研究报告称，数字在空间上是根据从左到右从小到大的“数字线”组织的。我们调查了这种空间数字组织是否取决于视觉经验。我们测试了先天性失明和晚期失明，以及在随机数字生成任务中被蒙上眼睛的参与者，在一个块中，他们的头在说出数字之前交替向左或向右转动。我们发现，“随机”数字的生成是有偏见的，根据头部转向的一侧。与标准的数字线一致，具有视觉经验的参与者在左转时产生较小的数字，而在右转时产生较大的数字。相比之下，没有任何视觉经验的参与者表现出相反的结果模式。这些结果表明，视觉经验的空间和数字表示，这是由文化差异的支持，在数字表示的发展中的作用，并提供了趋同的证据顶叶皮层的视觉驱动的组织。
Early studies on numeric cognition reported that numbers are spatially organised according to a left-to-right small-to-large ‘number line’. We investigated whether this spatial-number organisation is dictated by visual experience. We tested congenitally and late blind, and blindfolded sighted participants in a random number generation task where in one block their heads were alternately turned left or right before uttering the number. We found that the ‘random’ number generation was biased according to the side where the head was turned to. Consistent with the standard number line, participants with visual experience generated smaller numbers for left turns, and larger numbers for right turns. In contrast, participants without any visual experience showed the opposite pattern of results. These results suggest a role for visual experience in the development of spatial and numerical representations, which is supported by cultural differences in number representation, and provide converging evidence for visually driven organisation of the parietal cortex.
